Abstract: Metal-organic framework materials (MOFs) are highly porous entities comprising a multidentate organic ligand coordinated to multiple metal centers, typically as a coordination polymer. Crystallization may be problematic in some instances when secondary binding sites are present in the multidentate organic ligand. Multidentate organic ligands comprising first and second binding sites bridged together with a third binding site comprising a diimine moiety may alleviate these issues, particularly when using a preformed metal cluster as a metal source to form a MOF. Such MOFs may comprise a plurality of metal centers, and a multidentate organic ligand coordinated to the plurality of metal centers to define an at least partially crystalline network structure having a plurality of internal pores, and in which the multidentate organic ligand comprises first and second binding sites bridged together with a third binding site comprising a diimine moiety. Particular MOFs may comprise N,N′-di(1H-pyrazol-4-yl)ethane-1,2-diimine as a multidentate organic ligand.

Abstract: This application relates to transfer hydrogenation between light alkanes and olefins, and, more particularly, embodiments related to an integrated olefin production system and process which can produce higher carbon number olefins from corresponding alkanes. Examples methods may include reacting at least a portion of the ethylene and the at least one alkane via transfer hydrogenation to produce at least a mixed product stream comprising generated ethane from at least a portion of the ethylene, unreacted ethylene, and an olefin corresponding to the at least one alkane.

Abstract: The present disclosure provides base stocks and processes for producing such basestocks by polymerizing internal olefins. The present disclosure further provides base stocks, comprising low molecular weight polyolefin products, having one or more of improved flow, low temperature properties, and thickening efficiency. The present disclosure further provides polyolefin products useful as base stocks and or diesel fuel. In at least one embodiment, a process includes introducing a feedstream comprising C4-C30 internal-olefins with a catalyst system comprising a nickel diimine catalyst optionally in the presence of a solvent. The method includes obtaining a C6-C100 polyolefin product having one or more of a carbon fraction of epsilon-carbons of from about 0.08 to about 0.3, as determined by 13C NMR spectroscopy, based on the total carbon content of the polyolefin product.
